Lady Gaga is a stone cold professional, which is why she kept performing for 16 songs after one of her clumsy dancers bonked her on the head with a pole midway through her Born This Way Ball show Sunday in Auckland. According to fan site Gagamedia.net, Gaga continued performing after telling her audience, "I want to apologize. I did hit my head and I think I may have a concussion but don't you worry I will finish this show." Her make-up artist later confirmed through Twitter the singer had indeed suffered a concussion and is most definitely a badass.
